A student taking a midterm exam in Ancient History comes to two questions pertaining to a class that he missed, and so he decides to take a random guess on both questions. One question is a true and false question and the other is a multiple choice question with five possible answers. Describe how to calculate the probability to the true/false question.
There's only two outcomes (true or false) and one correct answer.
Therefore, the probability is 1/2 = 0.50 = 50%
Or you could say the odds are 50 50, ie there's a 50% chance of getting it right vs a 50% chance of getting it wrong.
A shop owner gave a 25% discount off the regular price of a table. The amount of the discount is $5.
What was the regular price of the mirror? (before discount)
Answer:
$20
Step-by-step explanation:
let the regular price of the mirror be 'x'
x*25/100=5
25x/100=5
cross multiply
25x=500
divide both sides by 25
x=$20
Which equation best describes the law of conservation of momentum?
O pi=PF
Op;>P
Op;
Answer:
Pi=Pf
Step-by-step explanation:
that's the equation for the law
Answer:
pi = pf
Explanation:
The law of conservation of momentum states that in any isolated system (=no external forces acting on it), the total momentum is conserved. This is also valid, for example, for a system consisting of many particles colliding with each other: during each collision between two particles, the total momentum of the two particles is always conserved, even if the momentum of each particle

If the equation ar+b=cr + d has no solution, like in the example below, what must be true about a b c and d?
Answer:
See below.
Step-by-step explanation:
For an equation like [tex]\displaystyle \large{ar+b=cr+d}[/tex] to have no solution, the equation has to be false.
To make an equation false, we let a = c. That’d make a and c have same value, when we transport cr to subtract ar, we’ll get 0.
So if a = c, the equation is [tex]\displaystyle \large{b=d}[/tex] now that we have b = d. The equation has to be false to have no solutions, hence b and d must not equal to one another.
Summary
When a = c, the new equation is b = d as ar and cr having same value, when subtracted, the remain is 0+b=d.b = d means that the value of b and d are equal but that makes the solutions to be infinitely many. Therefore, we cannot let b = d.From second, b ≠ d.a = c but b ≠ dLet me know if you have any questions regarding this question or for clarification.

I find the value of X and the measurement of DAB
Answer: What is the measure of ∠ DAB?
And we get that the measure of angle is 32 degrees.
Step-by-step explanation:
In circle C, mDE = 84°. Find each measure.
1. measure of angle EFD
Reason:
Use the inscribed angle theorem. Central angle DCE subtends the arc DE, so angle DCE = 84 degrees. Inscribed angle EFD is also subtending this same arc (DE), meaning we cut the arc/central angle measure in half to get 84/2 = 42.

A. acute
B. right
C. obtuse
Answer: C. Obtuse
Step-by-step explanation:
It is an obtuse triangle because one angle (the one which measures 110 degrees) is obtuse - it's greater than 90 degrees.

Answer:
W = 12Step-by-step explanation:
[tex]\sf\:\frac{W}{2} + 14 = 20\\\sf\:\frac{W}{2} + \frac{14 * 2}{1 * 2} = 20\\\sf\:\frac{W}{2} + \frac{28}{2} = 20\\\sf\:\frac{W + 28}{2} = 20\\\sf\:W + 28 = 20*2\\\sf\:W + 28 = 40\\\sf\:W = 40 - 28\\\boxed{\bf\:W = 12}[/tex]
Steps:
Find the LCM so that the denominator of W/2 & 14 is the same (LCM = 2)Now, add the 2 numbers in the LHS.Bring 2 to the RHS & multiply it with 20.Bring 28 to the RHS.By completing these steos, we'll get the value of W as 12.____________

√(11 +4 √7)
hi, brainly helper please solve this ASAP. Thank
Given that: √{11 + 4√(7)}
Let √{11 + 4√(7)} = √(x) + √(y)
Squaring on both sides then
= [√{11 + 4√(7)}]² = {√(x) + √(y)}²
= 11 + 4√(7) = x + y + 2√(xy)
= 11 + 2√(7 * 2²) = x + y + 2√(xy)
= 11 + 2√(7 * 2*2) = x + y + 2√(xy)
= 11 + 2√(7 * 4) = x + y + 2√(xy)
= 11 + 2√(28) = x + y + 2√(xy)
On comparing with both sides, we notice that:
⇛x + y = 11 →→→→Eqn(1)⇛2√(xy) = 2√(28)
⇛ xy = 28
We know that
(x-y)² = (x+y)² - 4xy
(x-y)² = (11)² - 4(28)
(x-y)² = (11*11) - 112
(x-y)² = 121 - 112
(x-y)² = 9
x - y = √(9)
x - y = √(3*3)
Therefore, x - y = 3 →→→→Eqn(2)On adding equation (1) and equation (2), we get
x + y = 11
(+) x - y = 3

2x = 14
Shift the number 2 from LHS to RHS, changing it's sign.
⇛x = 14/2
⇛x = 7/1
Simplify the fraction to get the value of x.
Therefore, x = 7Now, substitute the value of x in equation (1) then
x + y = 11
⇛7 + y = 11
Shift the number 7 from LHS to RHS, changing it's sign.
⇛y = 11 - 7
Therefore, y = 4Now, we have: x = 7 and y = 4
So,
√(x) + √(y) = √(7) + √(4) = √(7) + √(2*2) √(7) + 2
(Or)
Short Method:√{11 + 4√(7)}
= √{11 + 2√(7*4)}
= √{11 + 2√(7)√(4)}
= √[{√(7)²} + {√(4)}² + 2√(7)√(4)
[since, (a+b)² = a² + 2ab + b²]
= √[{√(7) + √(4)}²]
= √(7) + √(4)
= √(7) + √(2*2)
Therefore, √{11 + 4√(7)} = √(7) + 2
Answer: Hence, the simplified form of √{11 + 4√(7)} is √(7) + 2

Match the graph with the correct set of equations for the linear system. Then, classify the system as Consistent and Dependent, Consistent and Independent, or Inconsistent. (You should have two answers selected)
Answer:
Consistent independent
x + y = 0 and -x + y = -8
Step-by-step explanation:
Inconsistent: parallel lines, no solutions
Consistent dependent: same line, infinite solutions
Consistent independent: intersects at one point, one solution
Therefore, the pair of lines are Consistent independent
From inspection of the diagram:
One line has a negative slope and the other a positive slope.
One has a y-intercept of 0 and the other a y-intercept of -8.
Therefore, the solution is x + y = 0 and -x + y = -8
Because:
x + y = 0 ⇒ y = -x (neg slope, y-intercept of 0)
-x + y = -8 ⇒ y = x - 8 (pos slope, y-interecept at -8)
